San Bruno Mountain Weed Warriors

View More

At San Bruno Mountain Park
The last Friday & Saturday of every month, 9:00 AM - 12:00 Noon

Volunteer to save critical grasslands at San Bruno Mountain Park. Join the SSF Weed Warriors for fresh air and exercise and help them weed on the south slope of mountain. The south slope has large areas of grasslands that are critical to resident endangered butterflies. The focus is to remove invasive non-native plants.

Workdays are on the last Friday and Saturday of every month. So there are opportunities for those who would prefer a weekend workday. You're welcome on either day, or come both days - even better!

  • gloves provided
  • wear long pants and layers
  • wear long-sleeved shirt for protection
  • wear sturdy shoes with long socks
  • bring water!

RSVP required at least two days in advance of the event. Youth under 15 yrs old must be accompanied by an adult. Learn more and RSVP at the San Bruno Mountain Watch website.

Upcoming Dates

Canceled until further notice.
